The more memory your computer has, the more apps you can run simultaneously, and the better performance you get from your computer. Your iMac uses one of the fastest memory technologies available today — 1600MHz, Double Data Rate (DDR3) synchronous dynamic random-access memory (SDRAM) — ensuring that the processor is constantly fed with data without wasting clock cycles.
Important note: Every 21.5-inch iMac comes with 8GB of memory built into the computer. If you think you may need 16GB of memory in the future, it is important to upgrade at the time of purchase, because memory cannot be upgraded later in this model.
Serial ATA hard drives offer high capacity to store your apps, files and digital media.
For maximum performance, you can configure your iMac with 256GB or 512GB of flash storage instead of a traditional hard drive. Flash storage delivers up to 5x the performance of a traditional drive* — speed you’ll notice when you start up your iMac, launch an app or browse your photo library.
Fusion Drive combines 128GB of superfast flash storage with a traditional hard drive. And now it’s up to 50 percent faster than before.** It automatically and dynamically moves frequently used files to flash for quicker access. With Fusion Drive in your iMac, booting, copying files and importing photos are faster. Over time, as the system learns how you work, Fusion Drive makes your Mac experience even better. All while letting you store your digital life on a traditional, roomy hard drive.
Note: 1GB = 1 billion bytes; 1TB = 1 trillion bytes. Actual formatted capacity less.
*Testing conducted by Apple in September 2013 using pre-production 27-inch 3.4GHz quad-core Intel Core i5–based iMac units with 1TB of flash storage, and pre-production 27-inch 3.4GHz quad-core Intel Core i5–based iMac units with a 1TB 7200-rpm hard drive, all configured with 8GB RAM. Testing conducted using Iometer 2006.07.27 with a 30-second ramp-up, 5-minute run duration, 512KB request size, 8 outstanding IOs and 150GB test file. Average rotational media performance calculated by creating the test file on the outer, middle and inner sectors of the drive, and averaging the results from all three measurements. Performance tests are conducted using specific computer systems and reflect the approximate performance of iMac.

The wireless Magic Mouse — the world’s first Multi-Touch mouse — comes standard with your iMac. But if the look and feel of a Multi-Touch trackpad is more your thing, then choose to have Magic Trackpad shipped with your iMac instead, at no extra cost.
With Multi-Touch technology, Magic Mouse lets you control your Mac with simple gestures. It works wirelessly using Bluetooth technology, so you don't have to worry about cables or adapters cluttering your workspace. Built-in software lets you configure Magic Mouse any way you want.

It supports the full set of Apple gestures, so you can click, scroll, swipe, and rotate to control what’s onscreen. Magic Trackpad is made with smooth glass that feels great to the touch. And because it sits at the same height and angle as the Apple Wireless Keyboard, you can go from trackpad to keyboard in one seamless motion. Magic Trackpad works using Bluetooth technology and is completely wireless.
The wired Apple Mouse features a Scroll Ball that lets you move anywhere inside a document without lifting a finger. And with touch-sensitive technology concealed under the seamless top shell, you can choose either the versatility of a four-button mouse or the simplicity of a single-button beauty. The Apple Mouse is powered by a precision optical sensor.
The Apple Wireless Keyboard comes standard with your iMac. Its ultra-compact design saves space and lets you place your mouse comfortably next to your keyboard. Or you can choose the wired Apple Keyboard with Numeric Keypad. In addition, you can select the language of the keyboard and documentation.
All Apple keyboards feature an elegant, ultra-thin anodized aluminum enclosure with low-profile keys that provide a crisp, responsive feel.

For the ultimate in flexibility and to minimize cable clutter, choose the Apple Wireless Keyboard. Its ultra-compact size allows you to place your mouse comfortably next to your keyboard and fits on even the most crowded desk.

The wired Apple Keyboard with Numeric Keypad offers an extended layout that includes document navigation controls - page up, page down, home and end - and full-size arrow keys for playing games and scrolling through documents. Its numeric keypad is perfect for spreadsheets and finance applications. And two USB 2.0 ports let you connect your mouse as well as a high-speed peripheral such as a digital camera or printer.
The language option you choose will affect your keyboard layout and the documentation that comes with your Mac. Mac OS X is a multilingual operating system. During the set-up process, you can choose one of the many languages it supports for application menus and dialogs and for reading and writing text. Mac OS X also allows you to select your preferred language at any time using System Preferences.
Note: Your computer comes equipped with cables appropriate for the country in which you purchased it.
